Specification of Letters Patent.

Patented June 12, 191?.

Application filed October 30, 1916. Serial No. 128,471.

Coke, of which the following is a specificaapparatus referred to.

tion.

This invention relates to apparatus for discharging and preventing the undue breaking up of coke or fuel produced in vertical retorts and the like and has for its object to maintain the coke in as near as practicable the condition in which it leaves the retort, after being dry quenched and to convey away the coke in its unbroken condition for being loaded into trucks or barges or to be otherwise disposed of.

The invention is more especially applicable for use in connection with the apparatus for dry quenching coke distilled at a low temperature which is described in the specification filed pursuant to an application for Letters Patent made by me, No. 91791 of 1916.

In the apparatus described in the specification filed upon the application aforesaid receptacles are employed for the reception of the whole charge from the retorts and these receptacles are mounted upon a carriage adapted to pass beneath the retort set ting so that on the removal of the bottom plate of the retort the whole charge may descend under control into the receptacles and be there quenched out of contact with water.

The invention has for its object to dis charge the quenched coke from the receptacles of the apparatus referred to.

According to the invention the apparatus employed for the purpose comprises a frame having a mouth adapted to lie over the upper end of the receptacle of the quenching A curved plateor wall is mounted over the said mouth and a ram is provided to move upwardly through the length of the receptacle so that the coke in its upward movement is deflected by the curved plate or wall and discharged on to a conveyer by which the coke is then conveyed to a screen from which it is discharged. it

The apparatus is advantageously provided for the simultaneous discharge of two receptacles, the coke being deflected into a central position where the conveyor is disposed.

171w e ice comp i es the coostn tlon and the constructional features involved in the apparatus hereinafter described.

The invention is illustrated in the accompanying drawings in which Figure 1 represents a side elevation of an apparatus provided according to the invention,

Fig. 2 is an end elevation partly in sectionon the line m 1 (Fig. 1), while Fig. is a plan corresponding to Fig. 1.

In carrying the invention into eifect I advantageously provide the carrying frame a of a girder construction comprising longitudinal members forming between them a space a (Fig. within which the conveyer V or belt 7) passes to and fro, the longitudinal members of this girder construction being provided with riveted struts and braces o 0 and being extended at each end so that the respective ends of the carrying frame a may be suitably carried upon a hydraulic or electrically operated ram (Z. Each longitudinal member of the girder construction is advantageously provided at its upper extremity with a longitudinal angle iron 9,,

which extends the length of the carrying frame, one part of the angle iron section extending out laterally to serve as a seating upon which the carrying frame may seat or rest on the inner edgeof the respective rev.

ceptaclcs of the quenching apparatus of the prior application which are indicated in Fig. 3 in dotted lines, while the angle iron 9 may serve for the reception of a plate 0 of an angular curved sectionwhich on the outer sideis downwardly inclined and is adapted to enter within the mouth of the upper end of the receptacle 7 and on the other side is also inclined downwardly to such. an extent as to slightly overhang the edge of the conveyor or belt Z).

The conveyer or belt Z) is mounted upon the frame a and traverses the length of the frame, an electro-motor h and suitable reducing gear being mounted at one end through which motion is imparted to the driving drum around which the conveyer or belt passes and at the opposite end of the frame a a freely mounted drum 5 is provided within bearings capable of adjust ment in order to set the conveyor orbelt to the proper tension. The upper part of the conveyer or belt 72 is disposed immediat ly beneath the space or aperture a centrally provided in the frame a and inclined supr rting'p l y 63 are m t d p n the frame a for supporting the conveyer or belt I) at each edge where it passes beneath or within the space or aperture a referred to..

The apparatus illustrated in the drawings is provided for discharging from two receptacles f and accordingly the frame a is provided with two lateral apertures corresponding in Size to the mouth pieces of the receptacles f, the edges of which are formed re spectively by the outwardly protruding edge e of the plate 0, by the lower end of the curved metal plate 71 and by the vertical end supporting plates 76.

The vertical end supporting plates are fixedly mounted upon the frame a and serve for the support of the respective curved plate 71 at each end in positions determined according to the width of the receptacles f and they are mounted upon each side of the frame. The curved plates 71 are hinged at i. The end supporting plates 70 at each end are respectively provided with a curved slot /c for the reception of a screw threaded pin or fitting mounted at each end of the curved plate i in a position near its upper edge and adapted to pass through the curved slot 7: so that the respective ends of the screw threaded pins protrude through the slots 7111 in the supporting plates and a screw threaded clamping lever is mounted upon the re spective outwardly protruding ends of the screw threaded pins so that thus the respective curved plates 11 are fixedly secured in their adjusted positions. By such means the position or inclination of the curved plate 2' may be varied as may be required so that on the upward movement of the charge of coke or fuel from within the receptacles f it impinges against the respective curved plates 71 and is constrained by contact with the curved plates to fall inwardly a short distance on to the belt or conveyer b.

The hydraulic rams (1 upon which the frame a is mounted are adapted to have a determined movement within their cylinders by which when the receptacles f are brought into position immediately beneath the carrying frame, the carrying frame may be lowered so that the respective angle irons 9 may rest upon the edges of the mouths of the receptacles and the lower extremities of the curved plates 2' may also protrude in the mouths of the receptacles, so that thus on the upward movement of the coke from within the receptacles it may be discharged on to the conveyer in the manner described. For this purpose the receptacles are mounted upon a carriage to run on rails in the position indicated in Fig. 1 so that they may be conveniently brought from the position in which they are charged to the position in which they are discharged in the apparatus described.

For the purpose of discharging the receptacles discharging rams Z are provided in a position between the respective rails as indicated in the drawings, there being two rams corresponding to the number of receptacles f. The rams Z are adapted to have a vertical movement and to pass upwardly through the receptacles carrying with them the bottom door of the retort upon which the coke lies on its discharge from the retort in the use of the apparatus of the application referred to so that thus the charge in the receptacles is forced completely through the lateral apertures formed in the carrying frame a and conveyed away to the screen 32.

The screen 72 is provided of such shape that the COh'G or fuel from the conveyer or belt 7 is discharged into a central position at p, but the screen extends out laterally so as to afford ample area for the discharge of coke upon it; and in a central position on the screen a V shaped member ,1 is pivotally mounted at p, which may be moved into any angular position on the Screen, and maintained there by its own weight, to direct the coke or fuel to either side of the lower end or to any particular position according to the bosition of the sacks, truck or barge with reference to the screen.

The lower end of the screen 72 is supported by means of struts p which are disposed in a substantially horizontal position, and these struts are connected at one end to the lower end of the screen p while at the other end they are carried by means of vertical rods 77 extending from the upper end of the screen frame. These respective vertical rods 79 serve to carry a horizontal rod 12 at whose eXtremities the ends of the respective struts 79 are carried, grooved wheels 10 being provided at these respective extremities to run upon vertical guide rails 39 suitably carriecl upon a frame or otherwise sup ported so that thus as the carrying frame a is moved the screen 10 is also moved and is supported by means of the guide rails p Means are provided upon the screen 39 for the variation of its inclination. These means conveniently consist of two parallel screwed spindles p disposed beneath each side member of the screen frame. The respective struts p are connected to the nuts mounted upon these respective screwed spindles 39, while toward the lower end of the screen and beneath it, a spindle p is transversely mounted, upon whose extremities operating hand wheels are secured by which movement may be imparted to the respective screwed spindles through bevel gear, and thus th inclinat1on of the screen 7) is adjusted as may be required.

At the lower end of the screen a plate p advantageously extends to which are hinged a number of mouth pieces 77 of substantially U-shaped section each of which on its und r face has an arm p secured extending beneath and to the rear of its inner or lower end, by which it is hinged to the lower edge of the screen, and upon this arm 39 a weight is carried so that thus normally the mouth pieces 29 under the action of the weights stand in a perpendicular position to the face of the screen as indicated in the figures. The mouth pieces p however, are adapted to be brought into position so that they each may lie in line with the surface of the screen and serve as a chute through which the coke or fuel may be discharged from it. By such means the coke or fuel may be delivered from any particular position on the screen 72 and the member 22 may be disposed in such position as to direct the coke or fuel into the position where it is to b discharged.

I claim 1. An apparatus for discharging coke from the receptacle in which it has been quenched, comprising a frame having a mouth adapted to lie over the upper end of the receptacle, a curved plate or wall mounted over the said mouth, a ram adapted to move upwardly through the length of the receptacle, and a conveyer mounted to run within the frame and to receive the coke on its deflection by the curved plate or wall aforesaid and to quickly carry the coke away on its discharge on to the conveyer, substantially as described.
